Brian Cox and Robin Ince kick off the new series by tackling one of the greatest questions ever posed by science: which are better, bats or flies? Joining them for this unusual version of animal Top Trumps are a bat expert (Prof Kate Jones), a fly expert (Dr Erica McAlister) and Dave Gorman. Pitching arguably two of the least-lovable groups of creatures against each other, the battle for victory explores why we should favour flies or find bats beautiful. Although both are much maligned thanks to their association with some nasty diseases, Erica and Kate battle furiously to show why their respective species should be loved not loathed and how our planet would simply not be the same without them. Dave Gorman joins the panel in an attempt to help adjudicate. Executive Producer: Alexandra Feachem
